Description
FIELD OF THE INVENTION
The present invention relates to portable electronic devices, and,
more particularly, to Digital Living Network Alliance (DLNA)
enabled portable electronic devices.
BACKGROUND OF THE INVENTION
Recently, wireless data, entertainment and mobile communications
technologies have become increasingly prevalent, particularly in
the household and computing environment. The convergence of these
communications within the home and elsewhere has created a market
for merging many disparate devices into wireless network
architectures capable of seamlessly supporting and integrating the
requirements of all of these devices. Seamless connectivity and
rapid transfer of data, without confusing cables and wires for
various interfaces that will not and cannot talk to each other, is
a compelling proposition for a broad market.
To that end, communication industry consortia, such as the
MultiBand OFDM Alliance (MBOA), Digital Living Network Alliance
(DLNA) and the WiMedia Alliance are establishing design guidelines
and standards to provide interoperability of these wireless
devices. For example, Wireless 1394, Wireless USB, and native
IP-based applications are being development based on ultra wideband
(UWB) radio or WiMedia Convergence Platform.
In particular, the Digital Living Network Alliance (DLNA) is an
international, cross-industry collaboration of consumer
electronics, computing industry and mobile device companies. The
main objective of DLNA is the establishment of a wired and wireless
interoperable network of Personal Computers (PC), Consumer
Electronics (CE) and mobile devices in the home and on the road,
which may enable a seamless environment for sharing new digital
media and content services. DLNA is focused on delivering an
interoperability framework of design guidelines based on
internationally recognized open industry standards together with a
certification/logo program to officially verify and validate the
conformance and interoperability of compliant products for the
consumers.
DLNA defines three types of roles for devices in the DLNA network,
a digital media renderer role, a digital media controller (control
point) role and a digital media server role. A device having the
digital media server role is a component capable of storing and
sourcing media. A device that may have the digital media server
role may be, for example, a set-top-box, a digital video recorder,
or a personal computer (PC). A device having a digital media
rendered role may be configured to show to the user the content
provided to it by other devices. Devices configured as digital
media controllers (control point role) can initiate activities as a
third-party controller, for example, start the display of a media
from a digital media server device on a digital media renderer
device, i.e. control point devices are configrued to control how
and where to render content that is provided by the server. A
device can naturally assume one or more roles. For example, a
device that is configured as both the renderer role and the control
point may be termed a digital media player. Digital media players
can acquire media from a digital media server and play (render) it
to the user. A digital media player may be, for example, a
television or a home theater system.
SUMMARY OF THE INVENTION
Some embodiments of the present invention provide a digital living
network alliance (DLNA) enabled portable electronic device that
includes a DLNA device circuit and a DLNA management console
circuit. The DLNA device circuit is configured to attach the
portable electronic device to an existing DLNA network having at
least one existing DLNA management console so as to allow the
portable electronic device to be a source for data on the existing
DLNA network. The DLNA management console circuit is configured to
enable the portable electronic device to operate as a portable
management console for the existing and/or a new DLNA network.
In further embodiments of the present invention, the DLNA device
circuit may be further configured to transmit a request to the
existing management console requesting that the portable electronic
device be attached to the existing DLNA network as a DLNA device.
The DLNA management console circuit may be further configured to
transmit a request to the existing management console requesting
that the portable electronic device be given rights to act as a
secondary management console for the existing DLNA network once the
portable electronic device has been attached to the existing DLNA
network as a DLNA device.
In still further embodiments of the present invention, the existing
DLNA network may be managed from the existing management console
and/or the secondary management console.
In some embodiments of the present invention, the DLNA management
console circuit may be further configured to attach to the existing
DLNA network from a location remote from the existing DLNA network
and manage the existing DLNA network from the remote location. The
DLNA management console circuit may be configured to attach to the
existing DLNA network from the remote location over the Internet
using a wireless network and a DLNA proxy.
In further embodiments of the present invention, the DLNA
management console circuit may be configured to define the new DLNA
network including the DLNA enabled portable electronic device. The
DLNA management console circuit may be the portable management
console for the new DLNA network.
In still further embodiments of the present invention, the DLNA
management console may be further configured to receive requests to
attach to the new DLNA network from additional DLNA enabled
devices. The DLNA management console circuit may be further

embodied generally in any portable electronic device that includes
is capable of being attached to a digital living network alliance
(DLNA) that operates in accordance with at least one embodiment
described herein.
As discussed in the background of the invention, DLNA defines three
types of roles for devices in the DLNA network, a digital media
renderer role, a digital media controller (control point) role and
a digital media server role. A device having the digital media
server role is a component capable of storing and sourcing media. A
device that may have the digital media server role may be, for
example, a set-top-box, a digital video recorder, or a personal
computer (PC). A device having a digital media renderer role may be
configured to show to the user the content provided to it by other
devices. Devices configured as digital media controllers (control
point role) can initiate activities as a third-party controller,
for example, start the display of a media from a digital media
server device on a digital media renderer device, i.e. control
point devices are configrued to control how and where to render
content that is provided by the server. A device can naturally
assume one or more roles. For example, a device that is configured
as both the renderer role and the control point may be termed a
digital media player. Digital media players can acquire media from
a digital media server and play (render) it to the user. A digital
media player may be, for example, a television or a home theater
system.
Some embodiments of the present invention provide a fourth role for
DLNA devices as will be discussed herein. According to some
embodiments of the present invention, some devices in the DLNA
network may have a "management device" role. Devices having the
management device role may be configured to manage access rights to
the DLNA network, i.e., devices having the management device role
may be configured to manage which devices are allowed to attach to
the DLNA network and determine what the access rights for the DLNA
network are. For example, devices having the management device role
may provide configuration parameters to devices being attached. As
discussed above, a device can have more than one role without
departing from the scope of the present invention.
As will be discussed further below with respect to FIGS. 1 through
6, some embodiments of the present invention provide portable
electronic devices, management consoles and methods of operating
portable electronic devices in DLNA networks. As discussed herein,
the interest for generic solutions for Home Networking, such as
DLNA, has dramatically increased, and the first DLNA enabled home
electronic devices have been introduced to the market. Thus, it can
be assumed that the penetration of DLNA network will be rather
high, and there may be a need for simple and flexible means to
manage these DLNA networks.
Thus, according to some embodiments of the present invention, DLNA
devices may have a "management role." As used herein, DLNA devices
having the management role in accordance with some embodiments of
the present invention are referred to as "management consoles."
Thus, in accordance with some embodiments of the present invention,
a DLNA enabled portable electronic device may be configured as a
DLNA enabled device and/or as a DLNA management console. For
example, the portable electronic device may be a DLNA device that
can be attached to a DLNA network to, for example, be a data source
for the DLNA network, such as a source for streaming audio.
Furthermore, the DLNA device may include a DLNA management console
circuit according to some embodiments of the present invention
configured to operate the portable electronic device as a DLNA
management console. The DLNA management console circuit may be
configured to manage which devices are allowed to attach to the
DLNA network and determine what the access rights for the DLNA
network are. For example, the DLNA management console circuit may
provide configuration parameters to devices being attached. Thus,
in some embodiments of the present invention an "ad-hoc DLNA
network" may be established around the portable electronic devices
for temporary situations as will be discussed further herein with
respect to FIGS. 1 through 6.
Referring now to FIG. 1, a DLNA network 100 including a DLNA
management console 110 and multiple DLNA enabled devices coupled to
the DLNA management console 110 will be discussed. The main
objective of DLNA is the establishment of a wired and wireless
interoperable network of Personal Computers (PC), Consumer
Electronics (CE) and mobile devices in the home and on the road,
which may enable a seamless environment for sharing new digital
media and content services. DLNA is focused on delivering an
interoperability framework of design guidelines based on
internationally recognized open industry standards together with a
certification/logo program to officially verify and validate the
conformance and interoperability of compliant products for the
consumers. The details of DLNA are known to those having skill in
the art and will therefore not be discussed in detail herein in the
interest of brevity.
As illustrated in FIG. 1, the DLNA enabled devices in the network
100 include a personal computer 130, a television 150, a DVR/TIVO
160 and a laptop 170, all of which communicate with the DLNA
management console 110 in accordance with some embodiments of the
present invention. As further illustrated in FIG. 1, the network
100 also includes a DLNA enabled portable electronic device 190,
for example, a mobile terminal, according to some embodiments of
the present invention, which also communicates with the DLNA
management console 110. The DLNA enabled devices 130, 150, 160 and
170 can communicate with the management console 110 wirelessly
(WLAN). However, it will be understood that the connection may be
any connection supporting IP and UpnP without departing from the
scope of the present invention. As illustrated, the DLNA enabled
portable electronic device 190 communicates with the DLNA
management console 110 over a wireless link. Although embodiments
of the present invention illustrated in FIG. 1 include a personal
computer 130, a television 150, a DVR/TIVO 160, a laptop 170 and a
portable electronic device 190 all of which communicate with the
DLNA management console 110, embodiments of the present invention
are not limited to this configuration. Any DLNA enabled device can
be coupled to the DLNA management console 110 without departing
from the scope of the present invention. For example, any device
capable of storing and/or rendering audio and/or video image
content may act as a DLNA device in accordance with some
embodiments of the present invention.
Furthermore, although the DLNA enabled devices in FIG. 1 are
illustrated as being coupled to the DLNA Management Console 110,
the device may also be coupled to one or more of the other DLNA
devices without departing from the scope of the present invention.
For example, the PC 130 may be coupled to the DVR/TIVO 160.
As used herein, the term "portable electronic device" may include
any device having a cellular and/or local access wireless
technology. For example, a cellular radiotelephone with or without
a multi-line display; a Personal Communications System (PCS)
terminal that combines a cellular radiotelephone with data
processing, facsimile and data communications capabilities; a
Personal Data Assistant (PDA) that includes a radiotelephone,
pager, Internet/intranet access, Web browser, organizer, calendar
and/or a global positioning system (GPS) receiver; a gaming device,
an audio video player, and a conventional laptop and/or palmtop
portable computer that includes a radiotelephone transceiver. Any
portable electronic device capable of operating in accordance with
some embodiments of the present invention may be used without
departing from the scope of the present invention.
As further illustrated in FIG. 1, the DLNA management console 110
includes a device attachment circuit 115 and portable management
console circuit 117. Although only a single management console 110
is illustrated in FIG. 1, embodiments of the present invention may
include two or more management consoles 110 without departing from
the scope of the present invention. The device attachment circuit
115 may be configured to receive requests from a DLNA enabled
portable electronic device 190 to attach the DLNA enabled portable
electronic device 190 to the DLNA network 100 associated with the
DLNA management console 110 so as to allow the portable electronic
device 190 to be a source for data on the DLNA network.
As will be discussed further herein, according to some embodiments
of the present invention, the DLNA enabled portable electronic
device 190 may be permanently added (attached) to the DLNA network
100 or temporarily added to the DLNA network 100 as, for example, a
guest device. The access rights for the DLNA portable electronic
device 190 may be defined at the DLNA management console 110. The
device attachment circuit may also be configured to remove a DLNA
enabled device from and/or disable a DLNA enabled device in the
DLNA network 100. The status of the DLNA network 100 and the
attached devices may be viewed and changes via the management
console 110.
Furthermore, the portable management console circuit 117 may be
configured to provide rights to the DLNA enabled portable
electronic 190 that allow the DLNA portable electronic device to
operate as a portable management console for the DLNA network.
Thus, in accordance with some embodiments of the present invention,
DLNA enabled portable electronic devices 190 may be used as a
portable management console for local or remote management of one
or more DLNA networks 100 as will be discussed further herein.
In particular, in some embodiments of the present invention, the
management console 110 may be included in the DLNA enabled portable
electronic device 190 as will be discussed further with respect to
FIG. 2. The portable management console circuit 117 may be
configured to allow the DLNA enabled portable electronic device to
attach to the DLNA network from a location remote from the DLNA
network and act as a portable management console for the DLNA
network from the remote location. Thus, in these embodiments of the
present invention, the portable management console provided in the
portable electronic device 190 may define a new DLNA network
including the DLNA enabled portable electronic device 190, the
portable management console may include the management console for
the new DLNA network. The portable management console may then
receive requests to attach to the new DLNA network from additional
DLNA enabled devices, for example, additional portable electronic
devices as will be discussed further with respect to FIG. 3.
Thus, according to some embodiments of the present invention, the
DLNA management console 110 may provide a fourth role, the
management device role, for DLNA networks. As discussed above,
devices having the management device role, for example, a portable
electronic device, may be configured to manage access rights to the
DLNA network, i.e., devices having the management device role may
be configured to manage which devices are allowed to attach to the
DLNA network and determine what the access rights for the DLNA
network are. For example, devices having the management device role
may provide configuration parameters to devices being attached as
discussed in detail herein.
Referring now to FIG. 2, details with respect to some embodiments
of the DLNA enabled portable electronic device 190 of FIG. 1 will
be discussed with respect to the mobile terminal of FIG. 2. FIG. 2
is a schematic block diagram illustrating a DLNA enabled portable
electronic device 290 according to some embodiments of the present
invention. As illustrated in FIG. 2, the portable electronic device
290 includes a portable housing 200 and may include a display 214,
a man machine interface (MMI) 216, a speaker/microphone 217, a web
browser 218, a transceiver 212 and a memory 280, any of which may
communicate with a processor 295. Furthermore, portable electronic
devices 290 according to embodiments of the present invention may
further include a download control circuit 250 according to some
embodiments of the present invention, which also communicates with
the processor 295. The processor 295 can be any commercially
available or custom microprocessor.
As further illustrated in FIG. 2, the portable electronic device
290 communicates with a base station transceiver 260 connected to a
mobile switching center ("MSC") 270 in accordance with some
embodiments of the present invention. The transceiver 212 typically
includes a transmitter circuit and a receiver circuit, which
respectively transmit outgoing radio frequency signals to the base
station transceiver 260 and receive incoming radio frequency
signals, such as voice and data signals, from the base station
transceiver 260 via an antenna 205. The antenna 205 may be an
embedded antenna, a retractable antenna or any antenna known to
those having skill in the art without departing from the scope of
the present invention. The radio frequency signals transmitted
between the portable electronic device 290 and the base station
transceiver 260 may include both traffic and control signals (e.g.,
paging signals/messages for incoming calls), which are used to
establish and maintain communication with another party or
destination. The processor 295 may support various functions of the
portable electronic device, including a DLNA Circuit 250 configured
to manage the addition and removal of DLNA enabled devices
according to some embodiments of the present invention as will be
discussed further herein.
It will be understood that in some embodiments of the present
invention, the transceiver 212 may be a short range transceiver.
The short range transceiver may be, for example, a Bluetooth
transceiver, which may allow for high transfer rates of data over
relatively short distances. It will be further understood that
portable electronic devices 290 according to some embodiments of
the present invention may include a wireless transceiver and a
short range transceiver/transmitter.
In some embodiments of the present invention, the base station
transceiver 260 includes the radio transceiver(s) that defines an
individual cell in a cellular network and communicates with the
portable electronic device 290 and other portable electronic
devices in the cell using a radio-link protocol. Although only a
single base station transceiver 260 is shown, it will be understood
that many base station transceivers may be connected through, for
example, a mobile switching center 270 and other devices to define
a wireless communications network.
Although the present invention may be embodied in communication
devices or systems, such as the portable electronic device 290, the
present invention is not limited to such devices and/or systems.
Instead, the present invention may be embodied in any apparatus
that may be configured to attach to a DLNA network in accordance
with embodiments of the present invention.
DLNA enabled portable electronic devices 290 in accordance with
some embodiments of the present invention may have a versatile user
interface (UI) and a versatile security toolbox. These portable
electronic devices may also have a large set of communications
means, for example, Bluetooth, infrared (IR), WiFi, WiMax, Internet
access over Mobile Networks and the like. In other words, DLNA
enabled portable electronic devices according to some embodiments
of the present invention provide a useful platform for flexible
management of DLNA networks as discussed herein.
As further illustrated in FIG. 2, the DLNA circuit 250 includes a
DLNA management console circuit 251 and a DLNA device circuit 253.
Although these circuits and modules are illustrated in FIG. 2 as
separate circuits/modules, it will be understood that any of these
circuits/modules can be combined or split into multiple
circuits/modules without departing from the scope of the present
invention. The functionality of each of the DLNA management console
circuit 251 and a DLNA device circuit 253 will be discussed further
herein.
In particular, the DLNA device circuit 253 is configured to attach
the portable electronic device 290 to an existing DLNA network
(100, FIG. 1) having at least one existing DLNA management console
(110, FIG. 1) so as to allow the portable electronic device to be a
source for data on the existing DLNA network. In particular, the
DLNA device circuit 253 may be configured to transmit a request to
the existing management console (110, FIG. 1) requesting that the
portable electronic device be attached to the existing DLNA network
as a DLNA device. As discussed above, the portable electronic
device can be attached to the DLNA network permanently or
temporarily without departing from the scope of the present
invention.
The DLNA management console circuit 251 may be configured to enable
the portable electronic device 290 to operate as a portable
management console for the existing and/or a new DLNA network. In
embodiments of the present invention where the portable electronic
device operates as a "secondary" management console, i.e., in
addition to the management console 110 of FIG. 1, the DLNA
management console circuit 251 may be configured to transmit a
request to the existing management console (110, FIG. 1) requesting
that the portable electronic device 290 be given rights to act as a
secondary management console for the existing DLNA network once the
portable electronic device has been attached to the existing DLNA
network as a DLNA device.
Thus, the existing DLNA network (100, FIG. 1) may be managed from
the existing management console 110 and/or the secondary management
console provided by the portable electronic device 290. The DLNA
management console circuit 251 may be further configured to attach
to the existing DLNA network from a location remote from the
existing DLNA network and manage the existing DLNA network from the
remote location. The DLNA management console circuit 251 may be
configured to attach to the existing DLNA network from the remote
location over the Internet using, for example, a wireless network
and a DLNA proxy.
In embodiments of the present invention where the portable
electronic device acts as the management console for a new DLNA
network, i.e., the management console is an application running on
the portable electronic device 290, the DLNA management console
circuit 251 may be configured to define the new DLNA network
including the DLNA enabled portable electronic device 290. Thus,
the DLNA management console circuit 251 may be the portable
management console for the new DLNA network. Once the new DLNA
network is established, the DLNA management console 251 may be
configured to receive requests to attach to the new DLNA network
from additional DLNA enabled devices 284 as will be discussed
further below with respect to FIG. 3. In these embodiments of the
present invention, the DLNA management console circuit may be
configured to manage and/or monitor the new DLNA network.
It will be understood that although each of the circuit and modules
of the DLNA circuit 250 are discussed as being configured for
specific tasks, these tasks may be combined into one circuit or
module or split into additional circuits or modules without
departing from the scope of the present invention.
Details in accordance with some embodiments of the present
invention will now be discussed with respect to FIGS. 1 and 2. As
discussed above, the existing network 100 includes an existing
management console 110, for example, a personal computer,
associated with the network 100. The DLNA enabled portable
electronic device 190, 290 sends a request to the management
console to be added to the network as a DLNA device. For example,
the DLNA device circuit 253 of the portable electronic device 290
may send the request to the device attachment circuit 115 of the
management console 110. Thus, the attached portable electronic
device 190, 290 is initially "managed" from the existing management
console 110, where the status of the network can be viewed, access
rights 282 for the various devices can be managed and the like.
In some embodiments of the present invention, through the original
management console 110 the portable electronic device 190, 290 may
be give rights 282 to act as a secondary management console for the
network 100. As such the portable electronic device 190, 290 may
have two different roles within the network 100. In particular, the
portable electronic device 190, 290 may be both a DLNA enabled
device attached to the network 100 as well as a secondary
management console for the network 100. Thus, in accordance with
some embodiments of the present invention, the portable electronic
device 190, 290 may have the capability to attach to the DLNA
network 100 from a location remote from the DLNA network 100. For
example, the portable electronic device 190, 290 may be configured
to attach to the DLNA network 100 over the Internet using a
wireless network and a DLNA proxy. Accordingly, some embodiments of
the present invention may provide an ability to manage the DLNA
network 100 from a remote location as discussed herein.
Details with respect to some embodiments of the present invention
will now be discussed with respect to FIGS. 2 and 3. FIG. 3 is a
schematic block diagram illustrating a DLNA network 300 including a
portable electronic device configured as management console 390 and
a plurality of DLNA enabled devices 391 attached to the management
console 390 according to some embodiments of the present invention.
FIG. 3 further illustrates a second DLNA network 300'. The portable
electronic device 390 serving as a management console in the first
DLNA network 300 may only be a DLNA enabled device attached to the
network 300'. Thus, the portable electronic device can be attached
to more than one network 300, 300' in accordance with some
embodiments of the present invention.
As illustrated in FIG. 3, the DLNA enabled portable electronic
device 390 defines a new the DLNA network 300 that includes the
DLNA-enabled device 390 having an integrated management console,
i.e. having an application within the portable electronic device
(DLNA management console circuit 351). As discussed above, the
portable electronic device 390 is capable of managing, and thus
being part of, more than one DLNA network 300, 300' and, therefore,
it may be possible to establish flexible "ad-hoc DLNA networks"
around the portable electronic device 390 for temporary situations
as illustrated in FIG. 3.
In particular, additional DLNA enabled devices, for example, DLNA
enabled portable electronic devices 391 of FIG. 3, may request to
be added to the new DLNA network 300 where the portable electronic
device acts as the management console for the new DLNA network 300
in accordance with the standard DLNA procedures for attaching
devices. In these embodiments of the present invention, the
portable electronic device 390 may be configured to monitor and
manage the network 300 from the DLNA management console circuit 251
running the management console application in accordance with some
embodiments of the present invention.
In some embodiments of the present invention, a logical connection
between two DLNA networks may be provided. For example, a DLNA
portable electronic device 391 maybe granted access to the DLNA
network 300 by the management console 351 of the DLNA enabled
portable electronic device 390. In other words, the portable
electronic device 390 has the "management device" role in
accordance with some embodiments of the present invention. In some
embodiments, the user of the DLNA enabled portable electronic
device 391 may access content in the user's network by means of a
gateway concept.
Referring now to FIGS. 4 through 6, methods for operating a DLNA
enabled portable electronic device in a DLNA network in accordance
with various embodiments of the present invention will be
discussed. Referring first to FIG. 4, operations begin at block 400
by attaching the portable electronic device to an existing DLNA
network having at least one existing DLNA management console so as
to allow the portable electronic device to be a source for data on
the existing DLNA network. In some embodiments, the portable
electronic device may be enabled to operate as a portable
management console for the existing and/or a new DLNA network
(block 420).
Referring now to FIG. 5, a request may be transmitted to the
existing management console requesting that the portable electronic
device be attached to the existing DLNA network as a DLNA device
(block 510). Once the portable electronic device is attached to the
DLNA network, a request may be transmitted to the existing
management console requesting that the portable electronic device
be given rights to act as a secondary management console for the
existing DLNA network (block 515). The existing DLNA network may be
managed from the existing management console and/or the secondary
management console from a local and/or remote location (block
517).
Referring now to FIG. 6, a new DLNA network may be defined
including the DLNA enabled portable electronic device (block 630).
The portable management console may be a management console for the
new DLNA network. Requests may be received to attach to the new
DLNA network from additional DLNA enabled devices (block 635). The
new DLNA network may be managed and/or monitored using the portable
management console (block 637).
In the drawings and specification, there have been disclosed
exemplary embodiments of the invention. However, many variations
and modifications can be made to these embodiments without
substantially departing from the principles of the present
invention. Accordingly, although specific terms are used, they are
used in a generic and descriptive sense only and not for purposes
of limitation, the scope of the invention being defined by the
